Humor, what humor?

Okay, maybe a joke in bad taste for those seeking answers, but hey, no one comes here so I have to entertain myself :)

Please teach me, what is a snog?

Again, poor taste, but I needed a header. Doesn’t sound as good as Kirk’s ‘kiss’ version.

Click on the image for a larger view. Tennant here has darker hair-almost black, and he’s wearing a shirt I’ve not seen him wearing in the series to date. He’s wearing the Doctor’s suit, so unless he’s taken to ‘playing Doctor‘ I think it’s safe to reason this is a costume switch for episode 13.
